Abstract
A method of removing obscuring features of relatively standard size and shape from an image comprising the obscuring features, features of interest and background, comprising the steps of applying a geometric transformation to generate a transformed image with the obscuring features aligned with an axis of image; applying an attenuation algorithm to the transformed image to suppress features having a dimension in direction of axis of range appropriate to dimension of the obscuring features in similar alignment, and applying a reverse geometrical transformation to produce a modified image with obscuring features attenuated.
